Product details


Stardust company provide spherical refractory Nb521 alloy powder with high purity, low oxygen, high sphericity , smooth surface, no satellite spheres,  uniform particle size distribution. As the lightest refractory metal, niobium has the characteristics of high melting point, high temperature strength and high specific strength, and no radioactivity. It's the perfect thermal protection material and structural material for aerospace engines. Spherical niobium powder is suitable for laser/electron beam additive manufacturing,  hot isostatic pressing,  laser cladding, hot/cold coating and other processes.

 

We can not only provide relatively mature research on spherical refractory Nb521 powder but also provide 3D printing services, metal spheroidization services, 3D printing machines and devices .
